As one of the most well supported clubs in Europe, it is perhaps no surprise that some of the continent’s most highly rated talents have played for Celtic over the last decade or so.
Celtic’s recruitment strategy of sharpening up some of the world’s top young talents and selling them on at a big profit has proven extremely successful for both the club and the players, meaning you can find several of the Hoops’ former star players featuring in elite leagues such as the English Premier League, the Bundesliga and Ligue 1.
But which former Celtic players have the highest transfer value in 2025? Using popular football statistics website FotMob, these are the 14 ex-Celtic stars with the highest transfer value in 2025, from 14-1.
13. Virgil van Dijk - £25.6million
Out of contract at Anfield in the summer, the Dutch centre-back joined Liverpool for a record fee £75million just two-and-a-half seasons after leaving Celtic in 2017. He's won everything with the Merseyside club. Now 33, he's still valued at £25.6million. | SNS Group Photo: SNS Group
